Abstract
Official abstract text for this publication.
Provided is a method of producing an α-olefin polymer including a step of polymerizing one or more kinds of α-olefins each having 6 to 20 carbon atoms with a catalyst obtained by using a specific transition metal compound. By the method, an α-olefin polymer having a viscosity suitable for use in a lubricating oil can be produced on an industrial scale with ease, and further, the characteristics of the product can be widely changed through the control of reaction conditions.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of producing an α-olefin polymer, comprising: polymerizing one or more α-olefins, each comprising 6 to 14 carbon atoms, with a catalyst obtained by combining components (A) and (B): (A) a transition metal compound of formula (I): where R 1 to R 6 each independently represent a hydrogen atom, or an alkyl group having 1 to 4…
